“…Plant protein-based diets need to be adjusted for several limiting amino acids, minerals and vitamins, to mimic fishmeal and meet nutritional requirements for the various farmed fish species. Particularly the amino acids lysine and methionine, found to be low in several of the plant protein products on the market, have recently been in focus (Espe et al 2006). Even when levels of these amino acids were adjusted to meet requirements according to NRC (1993), the plant-based diets were found to result in enlarged lipid depots and liver sizes in Atlantic salmon, possibly signs of deficiencies in these amino acids (Espe et al 2007(Espe et al , 2008.…”

“…Supplementation of all-or high-plant diets with taurine in rainbow trout and hydroxyproline in Atlantic salmon (Aksnes et al, 2008) has been shown to benefit growth. In another study, Atlantic salmon grew well, especially regarding protein gain, on high-plant protein diets (wheat gluten and corn gluten meal) which were carefully balanced regarding amino acids and micronutrients, and supplemented with attractants to improve palatability (Espe et al, 2006). However, in Atlantic cod fed 100% plant proteins comprised of 50% wheat gluten, 36% soy protein concentrate and 14% bioprocessed soybean meal for 28 weeks , a progression toward a diarrhea-like condition, goblet cell hypertrophy and hyperplasia, as well as inflammatory changes were observed, mostly in the distal intestine but some also in the mid intestine.…”

The aim of this study was to evaluate the effects of the inclusion of Tenebrio molitor larvae meal in practical diets for gilthead sea bream on growth performance, nutrients digestibility, somatic and marketable indexes. Two separate trials were carried out: in the first a total of 153 gilthead sea bream (105.2 ± 0.17 g average initial body weight) were randomly allocated in 9 fiberglass 220 liter tanks (17 fish per tank) in an indoor water recirculating system. The fish were fed three isoenergetic and isoproteic diets formulated to contain increasing levels of TM meal inclusion and precisely: a control diet (TM0), in which fish meal was the main protein source; TM25 and TM50 diets, in which 25% and 50% of Tenebrio molitor larvae meal was added to the diet, respectively. These inclusion rates corresponded to 30% and 60% of inclusion on protein bases and 35% and 71% of fish meal substitution on protein bases for TM25 and TM50 diets, respectively. Each diet was randomly assigned to 3 tanks and the trial lasted 163 days. In the second trial the apparent digestibility coefficients of the 3 diets were measured on 72 fish randomly distributed to 3 digestibility tank-units (24 fish per unit, average body weight: 86.97±2.3 g) using an indirect method (acid insoluble ash).The group fed TM25 showed a higher (P < 0.05) final weight, specific growth rate, weight gain %, protein efficiency ratio, and a lower feed conversion ratio compared to the other 2 groups. The estimated apparent digestibility coefficients of crude protein and ether extract of the diets were lower (P < 0.01) in TM50 than in the other 2 groups. No significant differences have been found between TM0 and Tenebrio molitor larvae meal groups in morphometric and commodity-related characteristics, except for dressed yield and viscerosomatic index (VSI), that resulted the lowest and the highest, respectively, in TM50. The skin colour resulted to be affected by dietary inclusion of insect meal, especially at 50% of inclusion. The general evaluation of the results demonstrates that Tenebrio molitor larvae meal can replace fish meal up to 25% of inclusion in the diet for Sparus aurata without negative effects on weight gain, crude protein and ether extract digestibility, marketable indexes after 163 days feeding. On the contrary, when Tenebrio molitor larvae meal was included at 50%, nutrient digestibility, dressed yield, VSI and skin colour were penalized.

“…Dietary supplementation of amino acids improves the amino acid balance of feed that can improve the growth performance and profitability of the aquaculture industry (Li et al, 2009). Espe et al (2006) showed that through dietary supplementation of amino acids to the plant protein based diet can reduce the use of dietary fishmeal in the diet of Atlantic salmon without impairing the feed intake and growth performance. Lysine is one of the most limiting essential amino acid in the ingredients of plant origin (Mai et al, 2006;Gatlin et al, 2007).…”

A 60-day feeding trial was conducted to study the nutrient utilization and growth performance of Labeo rohita fed with T1 [DORB supplemented with phytase and xylanase (0.01% each)], T2 [ T1+ L-lysine(1.4%), L-methionine (0.4%), combination of EPA and DHA (0.5%)] , T3 [DORB supplemented with phytase (0.01%), combination of xylanase and cellulase (0.075%), L-lysine (1.4 %), L-methionine (0.4 %), combination of EPA and DHA (0.5%)] and T4 (commercially available carp feed) diets. Weight gain%, SGR, and FCR were similar (p>0.05) for the fishes fed with either T3 feed or commercial carp feed (T4), whereas PER was highest for the T3 group. A significantly higher apparent dry matter and carbohydrate digestibility were observed in the T3 group. Highest crude protein digestibility was observed in T4 group, though lipid digestibility was similar in both T3 and T4 groups. The activities of digestive enzymes were similar in T2, T3 and T4 groups, whereas the lowest activity of these enzymes were observed in T1 group. Based on the findings it is concluded that T3 feed (crude protein 18.18 %) is having comparable growth performance of Labeo rohita as compared to T4 diet (crude protein 32.01 %) due to higher In vivo digestibility.
